They don't even know how long that strain was going to make it with NO FISH. So treating for 8 weeks and then putting the fish back in the tank may not do a thing. It will get the numbers of ich way down but not necessarily eliminate it.

Quarantine can only help. That I am sure. However, what GreenSpottedPuffer said about QT time is interesting. For how long do you QT your fish? If what he said is right, my QT give me nothing.
